CoolFlex toolholders feature a coolant path that can be
switched from coolant-through-spindle to DIN style coolant simply by removing two setscrews.
According to the manufacturer, this feature can save thousands
of dollars when compared to the cost of tooling-up both coolant-
through and DIN coolant spindles.
CoolFlex holders are available for CAT40 and CAT50 spindles, in ER collet chuck and end mill holder styles. The collet chucks are available in sizes from ER16 to ER40 and are balanced to 18,000 RPM. The end mill holder styles range from ID 1/4” to ID 1-1/4” and are balanced to 10,000 RPM.
All CoolFlex holders are factory set for the coolant-through-spindle application and can be changed to DIN style by the user. CoolFlex collet chucks come with Techniks’ “Power Coat” nut that increases clamping power on the tool shank up to 75%.
